A volcano with basaltic magma would probably?
A)erupt with a violent pyroclastic flow
B)erupt with a gradual lava flow
C)erupt with explosions of tephra
D)not erupt at all, but remain in the
E)magma chamber and cool
i think its A
Basaltic magma is less likely to form a pyroclastic flow. I wanna say it's D. But not 100% sure. Sorry...
To determine the answer, let's analyze the characteristics of basaltic magma. Basaltic magma is associated with shield volcanoes, which are known for their low viscosity and low gas content. These volcanoes typically produce eruptions that are not violent and explosive, but rather characterized by a gradual lava flow.
Based on this information, we can eliminate options C and D, as explosions of tephra and no eruption at all are not typical for basaltic magma.
Now let's consider options A and B. A violent pyroclastic flow, like in option A, is more likely to occur with high-viscosity magmas like andesitic or rhyolitic magmas. These magmas have higher gas content, leading to more explosive eruptions.
Option B, erupting with a gradual lava flow, aligns with the characteristics of basaltic magma and shield volcanoes. Therefore, option B is the most likely correct answer.
To sum up, the answer to the question is:
B) erupt with a gradual lava flow.
